Endeavour Completes SEMAFO Acquisition

ENDEAVOUR COMPLETES SEMAFO ACQUISITION

George Town, July 2, 2020 – Endeavour Mining ("Endeavour") (TSX: EDV) (OTCQX: EDVMF) is pleased to announce the successful completion of the previously announced acquisition of SEMAFO Inc (TSX: SMF), effective July 1, 2020.

Pursuant to a court-approved plan of arrangement (the "Arrangement"), shareholders of SEMAFO received 0.1422 of an Endeavour ordinary share for each SEMAFO common share held. As a result of the Arrangement, SEMAFO has become a wholly-owned subsidiary of Endeavour. The common shares of SEMAFO will be delisted from the TSX on or about July 6, 2020, and have been delisted from the OMX. Endeavour will also apply to have SEMAFO cease to be a reporting issuer (or equivalent thereof) in all applicable Canadian jurisdictions. Further details regarding the Arrangement can be found in the joint management information circular of Endeavour and SEMAFO dated April 28, 2020 available on SEDAR under Endeavour's profile at www.sedar.com.

Endeavour also announces that effective July 1, 2020, Olivier Colom and Wayne McManus have retired from Endeavour’s Board of Directors and Helene Cartier and Tertius Zongo, both nominees of SEMAFO, are joining the Endeavour Board of Directors. Alison Baker will succeed Mr. McManus as Chair of the Audit Committee. Following the appointments, Endeavour’s Board is composed of nine members, of which eight are independent directors and non-executive directors: Chairman Michael Beckett, James Askew, Alison Baker, Sofia Bianchi, Helene Cartier, Livia Mahler, Naguib Sawiris, Tertius Zongo, and Sébastien de Montessus as executive director and CEO. To reflect SEMAFO’s entitlement to nominate three directors, Endeavour anticipates that it will add an additional independent non-executive director with a technical background to further balance the current board expertise and strength.

With regard to the management team, Benoit Desormeaux has joined Endeavour as President. Martin Milette has informed the Board that for personal reasons relocating to London is not feasible and therefore he will be pursuing other opportunities and will not transition to Endeavour as its Chief Financial Officer. Henri de Joux, Executive Vice President of People and Information Technology at Endeavour, is currently acting as Interim Chief Financial Officer, leveraging his experience as Chief Financial Officer prior to joining Endeavour.
